Eligibility
Key inclusion criteria
* Males and females aged 18 to 65 years
* Patients with diagnosis of CF as confirmed by at least one of the following:
* Documented sweat chloride = 60 mEq/L by quantitative pilocarpine iontophoresis test OR
* Documented sweat sodium test = 60 mmol/L OR
* Abnormal nasal potential difference test OR
* At least one well-characterized disease-causing genetic mutation in the CF transmembrane conductance regulatory (CFTR) gene AND
* Accompanying symptoms characteristic of CF
* Normal (or abnormal but not clinically significant) electrocardiogram (ECG)
* Normal intraocular pressure (IOP) between 10 and 21 mm Hg at Screening.
* Normal (or abnormal but not clinically significant) blood pressure (BP) and heart rate (HR) in the absence of any medications for hypertension; these will be measured after the subject has rested supine for 3 minutes; normal BP is taken to be 90 to 140 mm Hg systolic and 50 to 89 mm Hg diastolic; normal HR is taken to be 40 to 100 beats per minute (bpm)
* Able to communicate well with the investigator and to comply with the requirements of the entire study
* Provision of written informed consent to participate as shown by a signature on the volunteer consent form
* Nonsmokers for at least 180 days (6 months) prior to Screening
* Must be willing to abstain from alcohol and strenuous exercise during the 48 hours prior to Screening, 72 hours prior to initial dosing, and during the study
* Forced expiratory volume in 1 second (FEV1) = 50% predicted normal for age, gender, and height at Screening as per Knudson et al
* Stable regimen of oral CF medications, dornase alfa, and physiotherapies for the period 28 days prior to Screening; those subjects taking continuous (non-cycling) inhaled antibiotics for prophylaxis must be on a stable regimen of these drugs for at least 90 days prior to Screening
* Subjects must be in the off-phase of any cyclical inhaled antibiotic treatment regimen
* Must test negative for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) at Screening
* Male subjects who are sexually active must be willing to use effective barrier contraception (e.g., condom) during heterosexual intercourse from Day -1 through completion of the study and continuing for at least 90 days from date of last dose of study drug
* Male subjects must refrain from sperm donation from Day -1 through completion of the study and continuing for at least 90 days from the date of last dose of study drug
* Nonlactating females. Females on hormone replacement therapy (estrogen/progesterone) or contraceptive therapy must be stabilized on a product and dose for at least 90 days prior to Screening
* Females must have a negative serum gonadotropin pregnancy test at Screening and Day -1
* Nonpregnant females of childbearing potential must agree to use highly effective (<1% failure rate) contraception during heterosexual intercourse from Screening, throughout the study, and for at least 30 days following the last dose of study drug
* Glomerular filtration rate (GFR) of < 60 mL/min/1.73m2 at Screening (GFR to be calculated using the Cockcroft-Gault equation), and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) less than or equal to 3× upper limits of normal (ULN)
* Chest radiograph at Screening without significant acute findings (e.g., infiltrates [lobar or diffuse interstitial], pleural effusion, pneumothorax); or chest radiograph, CT, or MRI obtained within the 90 days prior to Screening without acute findings or significant intercurrent illness; chronic, stable findings (e.g., chronic scarring or atelectasis) are allowed. A chest radiograph obtained and interpreted between Screening and Day 1 is also acceptable for determining eligibility.

Key exclusion criteria

* Subjects who routinely use inhaled hypertonic saline must discontinue use for at least 14 days prior to clinic admission and for the duration of the study
* Use of trimethoprim or high dose ibuprofen (> 800 mg/day) during the 28 days prior to first dosing

* Subjects requiring any of the following drugs in the 28 days prior to Screening: diuretics (e.g., spironolactone, amiloride, thiazide), ACE inhibitors, angiotensin receptor blockers, oral corticosteroids, or medicines for hypertension
* Donation or loss of greater than 400 mL of blood in the period 90 days (3 months) prior to Screening

* Hemoglobin levels < 120 g/L in females or < 130 g/L in males taken at Screening and at Day -1
